The pumps MVA and MVB are intended for a rating of fireproof and unexplosive pure liquids or liquids with trace pollution with low degree of viscosity.
The pumps MVA and MVB find application in:
- systems of water supply and water systems
- systems of increase in pressure
- systems of supply of a copper with feedwater and condensation systems
- klimatizatsionny systems, systems of central heating and circulation of water
- industries
- fire - prevention installations

MVA and MVB – centrifugal one - stage monoblock pumps in which working wheels of the pump and the engine are established on the general to a shaft. The most essential sizes of the case correspond the EN 733 standard (the former DIN 23255 standard). The soaking - up branch pipe and a pressure head branch pipe conform to ISO 7005 - 2/PN 16. The pumps MVA and MVB are directly connected with the electric motors conforming to the VDI and IEC standards. Due to the modular structure the engine, a sealing cover and a rotor can be taken out without removal from system of the spiral case. The monoblock pumps MVA and MVB easier and less in comparison with normal centrifugal pumps with similar hydraulic characteristics.
